To all whomV t may concern:

Be it known that I, CHARLES H. Nirscn, a citizenl of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and' useful Improvements in Machines for Pressing Necks in Boxes, of which the following is a specification.

My invention relates to machines for making paper boxes, and particularly to a machine for pressing the necks in position in necked box bodies.

My invention comprises Va machine of the type commonly known as a neck presser in the art, an example of which is disclosed in the patent to Philip S. Smith #MSA-29. The machines of this kind are used. in the production of the type of paper box in which a vertical strip or neck is glued to the inside of the bodyportion of-thebox and projects above its upper edge to form a flange over which the cover is placed with its edges buttingthe edges of the box body, producing al flush side. In introducing necks in box bodies, the glue is applied to the inside of the body and the neck inserted by hand; Originally, the entire process ofl fixing the neck inposition was performed by hand. Subsequently, neck pressers were developed, in the use of which it is only necessary for the operator to loosely locatel the neck in the glued box body and to position the body with the neck therein over a form. The pressis then applied to the box on the form and the neck pressed firmly into contact with-the box body. T his method ofv procedure not only insures continuous, even contact but avoidsl finger marks Vand smears incidental to handling, in addition to considerable speeding up the process. By this method, however, the box is both inserted and removed by hand, necessitating considerable manual. labor and slowing. Iup the press action because the press must be held in open position while the operator removes a boxtherefrom and inserts another in its place.

An object of my invention is to produce an improved machine which will be much more rapid in operation,y both because of the-fimproved arrangement of the parts, and because ofl additionalv features whichy elimi- Specication of Letters Patent.

nate part of the handling of the boxes by the operator. @ne improved feature is the location of the presser table in an approximately vertical position, preferably slightly inclined rearwardly so that the boxes will remain therein through gravity. This enables the operator to place the box body in the ypress without reaching over the table, making the path of the box from the feed table to the press much shorter and the operators work correspondingly quicker.

l have also provided means for automatically removing the box from the presser, entirely eliminating any handling thereof the box is once inserted in the press. This means includes both a device fori ejecting thebox fromthe press, and a convenient conveyer for carrying the box to a delivery point at one side of the press.` l have also arranged my press, ejector and conveyer in such a way that the ejected box falls on theconveyer by gravity,

this arrangement permitting the use of a` very simple ejecting and conveying mechamsm.

Furthermore', l provide a singlefixed form mounted on the press, upon which the operator locates the box body, with the neck loosely placed therein, while the press is open. After the box is pressed, the ejecting mechanism removes it from the form, leaving' the latter readyfor the next box body and neck. This method of operation enables the operator to handle the boxes very rapidly, as they are light and readily positioned on a firmly mounted form. l have so constructed'my press that a form of any desired sise and shape may be quie :ly and easily substituted for the form in the press and the press members readily adjusted to the new form or replaced by other members suited to cooperate with the new form.A

l.' have also produced an improved press mechanism. have provided a single driving element for all four presser blocks of each press, simplifying-.the drive substantially and assuring perfect synchronization. l also reciprocate all of the presser blocks, as it Ais only necessary, with this construction, to move each block half the distance required in the Smith neck presser in order to provide the same amount of clearance. Fur-V LILO have made the two presses entirely independent of each other save for a common thel1 T drive shaft, and have arranged the parts' so thatV they may readily be removed and replaced, the whole tableand'its mechanism beinggreadily removable. l also have provided an improved resilient mounting for the presser blocks, adapted for adjustment to insure even pressure throughout the block.

The vertical arrangement oi my press has Vfacilitated the mounting in the rear thereof Y and economizes Lioor space while it iacili-V tates rapid Vhandling-g' oi the boxes.

l/Vhile certain features oi myV invention are improvements on the Smith neck presser, it will be apparent that many oi"- them are distinct departures therefrom, and are applicable broadly to other presses or similar machines of various kinds. V

' Other objects and advantages of my invention" will be apparent from the 'following description taken in connection with the accompanying drawings, in which:

Figure l broken away,

Fig-.Q is an end vView from the right hand side of Fig. l,

Fig. 3 is al plan view oi' the table with the presserA block structure removed from the lett hand press, Ypart oi the table being broken away to showthe drive,

Fig. ll is a top view of the table and the driving mechanism, the right half being shown in plan, the left half in transverse horizontal section through the center of the press and through the Acenter of the drive shaft, and Y v Fig. 5 is a detail plan view ot the presser block mounting, the mounting head being shown in central horizontal section.

` Similar reference numerals refer to similar parts throughout the drawings.

My neck presser is carried by a frame consisting preferably of end members i0 and 1l upon which is removably mounted by bolts or screws l?, the press table 13, in approxiymately vertical position, being preferably tilted slightlybackward. Ourthe trent oic the table is mounted presser mechanism which may consist of any prei-'erred number of presses, two being shown in the form illustrated. These presses are exact duplicates and independent of each other. Each comprises a plurality of presser blocks lil, ordinarily wooden blocksproperly shaped to lit t-he contour'of the bonito be pressed and which may carry on their inner faces pads l5 ci any desired material. Each block is held in aclamp 16 having` upper and lower is a front view v )arts beine' jaws7 a set screw 17 being mounted in the upper jaw to adjustably clamp the block 1n position. As shownin F ig. 5, each clamp carries two studs 18, removably mounted on the rear face oi ihe'clamp, as by threading them into socletstherein. Each stud has a head 19 slidably mounted in a chamber 2O in the presser block carrier head 2l', the

.iront end oi the chamber being apertured Yreadily adjusted by means oi said plug.

Each carrier head 2l is adji'istably mounted ona longitudinally slotted slide 245 in any desired way. l preferably use a bolt 2.5, passing vertically through the carrier hear and the slot to clamp the carrier head 2l adjustably on slide 211i. Slide 24 rests upon the surface table 13, or, if desired, upon i a slightly raised portion thereoi, said table being cut away beneath the slide slot to pro- Vvide clearance for the head of `the carrier bolt. This head is preferably elongated in shape, being normally located transverse to the'slot, but as it is narrower than the slot,'

the carrier may be readily removed' by loosening the boltfand rotating it through a quarterrevolution to bring t ie head in line with the slot. Slide 24C reciprocates in ways of any desired construction. l prefer to provide a pair of ways?? suitably formed to accommodate the edges ofthe slide, which may be bofeled, tie ways being removably mounted on table 13, as by screws. lt will be apparent that the slide and presser block carrying mechanism may vbe entirely removed by the removal of waysQl, facilitating the repair and replacement ot parts. (lbviOuSly, various other methods of mounting the presser blocks may used without affecting the operation oi other parts my invention, and the specilic type oi mounting shown is applicable to a variety of macl'xines.

Each of the slides 2l has projecting downwardly from its forward end a hub 28, best shown in Fig. d, carrying a stud 29, on which is mounted a roller 30, into groove in the face et disk cam 32, lying parallel to and below the suriace of the table, said cam being mounted on stub shaft sockets in the table and housing, providing. for positive location of the shaft in place.

when the housing is in position and facilitatingthe ready removal thereof upon removal of the housing.

I preferably provide a removable form block 38 which is mounted on the table between the presser, blocks in any approved manner, such, for instance, as by screws threaded into sockets provided in the table, or by mounting. studs on the table, fitting into sockets in the block. l also provide ejecting means for removing a pressed boa body from the block. lhis means may include a plunger rod 39, passingthrough a longitudinal guide passage in shaft 33 and through a registering bore in block 38, the outer end of plunger 39 carrying an ejeoting late 40 normall restino` in a countersunk.

recess` in the face of block 38, the ejector plate being. ifdesired, threaded on or otherwise removably attached to, plunger 39 to facilitate detachment of the plate and removal of the block when a, new block is to be substituted. The ej ector is reciprocated to remove pressed box bodies by means of an ejector lever connected by link lf2 to a collar 43 threaded on plunger 39 and held in adjusted position by nut 44. rlhe plunger can be adjusted to stl.

various heights of block 38V by varying the location of collar l on 'the plunger and, if desired., the plunger 39 may be entirely removed to change blockBS by unscrewing it from collar 4:3 and nut 44;. The ejector lever d1 is pivotally mounted on a bracket 46 mounted on casing 37, the pivot 45 carrying for convenience the end of the ejector lever l1 of the adjoining' press. liever Lil' may be operated by various means. .l prefer to form gear teeth l? on the periphery of cam 32, meshing 1fvith a pinion i8 mounted on stub shaft 49, which is shouldered and mounted in the same manner as shaft 3B in sockets in the table 13 and casing 37. lifounted on. and preferably integral Ywith, pinion-f8 is a cam disk 50 having a periph orally upstanding cam ridge V5l which is of theV same height throughout except for a short depression therein at 52. A. rod 53 slidable in a, bore in the casing 6.7 rests on the face of the cam ridge and has at its upper end fork 5d carrying a pin passing through a short slot in the eject-ing lever The lever is normally pulled toward table 1S by spring 55 attached at one end to said lever and at the other end to the casing, preferably being attached for convenience to a projection on the end of stub shaft 49.

Both presses are driven by a single drive shaft 56 mounted in the rear of table 13 in bearings in Yframe members l0 and 1l. Worms 57 are mounted on drive shaft 56 adjacent Worm gears 35 and mesh therewith through apertures in casing 8?. lf desired.

however; casing?` may be formed to act as a housing for Worms 57. Shaft 56 maybe driven in any approved Way. lf have shown one form of drive. including a drive pulley 56 mounted loosely on the shaft, having the usual spring-pressed conical clutch 59 nor mally in engagement therewith. As shown in Fig.y l, a fork 60 engages collar 6l, tho clutch member being controlled through link 62 connected to the fork and pivoted on starting lever 68, the rear end of which is provided ivith a bearing on frame member l0, the handle end of the starting lever extend ing through slotted holder 64- at the front of the frame, a shoulder 65 in said` holder serving to retain the starting` lever in position when the clutch is thrown out against the action of spring 66. Pulley 58 may be driven from any suitable source of power. l have shown a motor 67 mounted on the frame of the machine and connected by a belt to the pulley.

l also provide a conveyor for removing the pressed boxes. This conveyor may be in the form of an endless belt 68, located lin frontof and adjacent the lower edge of table 13, the belt running at its left hand end over roller 69, preferably mounted von an adjustable bracket 70, carried by the frame member l0. The other end of the belt conveyer runs over roller 7l mounted on shaft 72, carried by brackets 73 on end frame ll. shaft 72 being driven from drive shaft 56 in any desired manner. l have disclosed a gear train for this purpose., comprising' a' pinion 741 mounted on the end of shaft 56 and meshing ith pinion 75, carried by a stud on frame member ll, Which in turn meshes with pinion 76. also mounted on a stud on said frame member. A bevel gear 77 is fixed on the outer side of said pin ,v 7 6 and meshes with bevel gear 'i8 mounted on shaft 72. Housing 79 attached to frame member l1 is provided to protect the gear train. A neck gluer 66 may be mounted in any desired manner at the rear of the frame and adjacent table Si. which is mounted onV brackets along the right hand end of thc machine. and extends to the front thereof, so that the gluer operator may lice the loosely necked boxes along the table to the neck presser operator.

l also provide means for the falling boxes ejected from the press to con veyer belt 58. l

ln the form shown. sai/5. means consists or a board or plate 82 located adjacent the outer edge of the belt` and ing table 1.3, the board boing preferably .sup-

ported by brackets Slattaohed to the table 13. This board 82 not only .guides falling` s boxes to the conveyor, but` prevents their bein@ knocked off the convever dur-in 'the travel thereon.

ico

1While I have shown the conveyor as exsirable thcrebeyond to convey the pressed boxes to thenext operator. 1n the operation of the machine, a suitable form block 38 is first fixed inplacein each press and ejector plate a0 fastened in position. Bolts .25 are loosened, and the rier heads are slidl inwardly until presser blocks 14. are in proper relation to block 1n pressing narrowT or small boxes, a convenientmethod of arranging presser blocks 14 isto have the leithand end oi each blocs: located against the tace oic the adjacent presser block, the right hand end or each block when the press isin closed position projecting beyond the end ot tie block to its right. 1n this manner, b^ having dimensions smaller than the lei ,u of the presser block may be properly pressed. Clamp screws 17 facilitate ready adjustment of the blocks. This method oi arrangement is, oi course, applicable only to sided boxes. The carrier heads 21 are then clamped in position by tightening bolts 95 and the presser is started by manipulating the starting handle 65 to throw in the clutch so that drive shaft 56 rotates cams through Worm gears V57. Presser carrier heads 24- are reciprocated through rollers 30, the cam slot 31 beine so shaped that the slides of each press are simultaneously moved outwardly and inwardly, producing opening and closing motions ol blocks Ejector plate 40 Vis normally held in the recess in block 38, but when the press starts to open, rod 53 drops into recess 52 in cam flange 51, depressing` the ejector lever 4:1., Which pushes plunger 39 outwardly. lfhe continued rotation or cam pushes ro 53 "l o up out or recess 52,-retracting the plung s' and preparing the block for the reception oit a box. The operation of adjacent presses is so timed that the ejectors Work alternately.

The operator,'vvhen the press is in motion, takesya box body, With the neck loosely inserted therein, from table 81 Where it has been placed by the gluer operator, and positions it on a block 3S as soon as the ejector plate 40 has returned to position in the block. The press then closes on the box, the adjacent press simultaneously opening to eject its box andreceive another. V"When the press closes, blocks 14e are resiliently pressed against the sides of the box by springs 22,

andby regulating the pressure oi' the springs by means of screw plugs 23, the amount of pressure on the box sides may be regulated, and uneven pressure at opposite ends may be avoided, thus compensating for variations in the springs.

1t Will also be noted that the connection between blooks 14 and carrier heads 21 is entirely exible, allowing the blocks to move vertically as Well as horizontally, permitting the block faces to accommodate themselves .t0 the irregularities inv the box, This is of particularV value when the boxl is Vnot rectangular in form, and the block is shaped to conform thereto.v f

When the box has been pressed and the press opens, ejector plate 4:0 rises, pushing the box oil the block 38. When free of the bloox, the box falls to conveyer bolt 68, beingV guidedtheret@ by board 82, and is then carried to the left hand end oi' the machine, Where it may bedisposed of in any desired Way, such as by. falling into a receptacle, by being` carried on by another conveyer or beingreceived by the succeeding operator. As soon as the box is ejected, the operator immediately replaces it with another box. rlFhis operation can be performed at a relatively rapid rate of speed, as it consists simply ofpicking up the light box body and positioning. it on block 38, theV removal oi the box from the press and from the machine being automatic. .The machine is also arranged so that the box can be placed on the form block by a relatively short motion of the operator and Without leaning over the table, as Was necessary with the former type of press. f

1t will be apparent that the partsare so arranged that they can be readily removed and replaced. fis-.above pointed out, each presser block unit may beremoved byitself Without disturbingv the rest of the machine, and the Ways Which'are subject to considerable Wear, may be'y'very readily replaced. The entire drive mechanism may be exposed by detaching the plungers 39 andthe rear casing 37 and removing table 13. i Casing'37 may also be divided'in sections, so that parts thereof may be removed and the operative portion of the mechanism readily taken out and repaired or replaced. Each press isa complete unit, and any derangement thereof may be repaired, Without stopping the other press, by disconnecting the deranged press from the drive through the removal of Worm gear 35. o
